Extron Electronics Matrix 50 Series - Manual (Page 12)

Introduction, cont’d
Matrix 50 Series Switchers • Introduction 1-4
control program also has an emulation mode that lets you create a switcher
configuration file at the home office and then download it for use by the
switcher on site.
• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s
SIS for easy programming and operation.
Audio gain/attenuation — Users can set the input level of audio gain or
attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front
panel. Individual input audio levels can be adjusted so there are no
noticeable volume differences between sources (figure 1-2).

Global memory presets — 12 global memory presets are a time-saving feature that
lets you set up and store input/output configurations in advance and then
recall those configurations when needed with a few simple steps.
Switching flexibility — Individually buffered, independent matrix switched video
outputs with audio follow and audio breakaway for models with audio.
• Any input to any or all outputs
• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to
source at the same time.
• Audio follow — Audio can be switched with the corresponding video input.
This feature allows any audio signal to be selected with any video signal
simultaneously to one or all outputs in any combination. Audio follow
switching can be done via front panel control or under RS-232/RS-422 remote
control.
• Audio breakaway — Audio can be broken away from its corresponding
video signal. Audio breakaway switching can be done via front panel control
or under RS-232/RS-422 control.
Remote control — The Matrix 50 switchers are remote controllable, using the
MKP 1000 master control keypad and any combination of MCP 1000 slave
control panels and/or MKP 1000 slave control keypads. The remote control
devices are easy to use and provide tactile buttons for quick selection. Each
MCP 1000 can be used for one-touch switching for a particular output and
selecting global presets. Each MKP 1000 dedicated to an output can be used
to select a different input for that output or to select a preset.
